Any good teen tv shows?

I've been looking for good teen tv shows to watch. I love shows like
Glee, Connor Undercover (about a 15 year old spy who protects a 15
year old presidents daughter), Flight 29 Down (about a group of teens
who get stranded on a island) and H2O just add water (three teen
mermaids) so something like those shows would be great.

i've watched shows like Gossip Girl, 90210 and One Tree Hill and i
wasnt that crazy about them.

thanks!
